The Largest Source of Heat Energy

Heat Energy Source, Solar Energy Short Question Answer

The Largest Source of Heat Energy:

Heat energy from the sun is known solar energy. Rays from the Sun heats the surface of the earth, the oceans and the air above.Taking a hint capacity of natural solar heating, scientists
Solar cells made ​​from which we can get electricity. When Sunlight touches the solar cells, it causes a chemical reaction and Electricity generated.  

Solar panels can heat water and cook food And solar cells can even run a car. Fossil fuels such as oil
Should be mined from the earth, and one day be used in them All up. But solar power is not over for millions of years.

Heat Energy-How is heat transferred from one thing to another

Heat Energy-How is heat transferred from one thing to another?

Ans:  heat is transferred by conduction, convection and radiation. Conduction means transfer of energy one molecule to molecule below. Whenever two materials approach each other heat flows samovar cooler material by conduction. Conversion is when the heat source heats a liquid or gas due to the movement of currents in a gas or liquid. This water is what water boils. Radiation is the transfer of heat in straight lines like a ray of sun. Direct radiation from the sun can be dangerous because it contains ultraviolet funds that harm our skin.
